All eligible patients will be assigned to a single group. They will be asked to fill out a survey to determine their level of anxiety prior to the procedure. Participants will then proceed the same as non-study patients to see the nurse for a pre-operative assessment. After seeing the nurse, patients will see the surgeon for the procedure. Most of the data (blood pressure, heart rate, breathing rate etc.) is collected during the procedure. During procedural sedation monitoring is performed as usual but study patients will have capnometry added to the standard of care. Capnometry is a way of examining your breathing. It is the measurement of the carbon dioxide in the air that you breathe out through you nose. After the procedure is complete patients are transported to recovery where they must remain for a minimum of 30 minutes prior to discharge. The nurse in recovery will monitor you recovery continuously during your stay. The nurse will also apply a standard recovery score to your recovery every 5 minutes to track your progression. Once you are recovered from the procedural sedation you will be asked to complete a short questionnaire about your procedural sedation experience. After discharge patients will be contacted by phone 24 to 48 hours later to review a final questionnaire.
